BEARING.

Specification of Letters Patent.

' Application filed September 9, 1912. Serial No. 719,353.

To all whom t may concern.'

Be it known that I, WALTER I. Crim-NICK,

a citizen of the United States, and a resident of Trenton, in the county of Mercer and State of New Jersey, have invented a new and Improved Bearing, of which the following is-a full, clear, and exact description.

rIhis invention relates to bearings for use in connection with prime movers, and for other like purposes, and has reference more particularly to a device ofthis class which comprises relatively movable' members adapted to receive the Babbitt metals or brasses between the same, and provided with an adjusting device operable to spread the ,members, means being provided for ,holdingthe members together 1n the usual manner.

The object of the invention is to provide a simple, inexpensive and durable bearing which can be applied to all the various purcompact in form, and comparatively light in weight, and which canbe rapidly and easily adjusted by a simple manipulation, to take up wear and to fit the bearing exactly to the member journaled therein.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set j forth in the claims.

Reference is tobe had to the accompanyingvdrawings forming a part of this specifiin which similar characters of reference indicate corresponding parts in all the views, and in which.-

Figure 1 is a side elevation of the end of a connecting rod having an embodiment of my invention applied thereto; Fig. 2 is a similar view showing certain of the parts in different positions; Fig. 3 is a plan view of the bearing; Fig. 4 is a transverse section on the line 4-4 of Fig. 1; and Fig. 5 is a per-v spective view of a detail of the structure.

Before proceeding to a more detailed explanation of my invention, it should be clearly understood that .while I havev ex-v emplied it in the embodiment shown herewith as appliedtoaconnecting rod, the invention can be employed for numerous other purposes, and can be'constructed'in different sizes, shapes and proportions. Needless to say, the actual bearing metals employed with the bearing may be of different kinds, consisting for example, of Babbitt metals, or

brasses. ignated these parts as bearing metals.

Certain of the details of construction shownfor example herewith, form no part of the invention, and can be varied in ac- Patented AMay 13, 1913.

For simplicity, I have herein-descordance with individual preference or spef cial conditions, without departing from the underlying spirit of the invention: 4

Referringmore particularly tothe drawings, the bearing illustrated for example is located at the end of a connecting rod ,10,y

which, at the extremity, is laterally extended to form one of the bearing members 11 having in the outer face thereof a substantially semi-circular recess 12in whichis ,received one of the bearing met-als 13. yThe second bearing member, 14, is disposed against the member 11, rand has lin theinner face thereof a substantially semi-cylindrical recess 15 registeringwith the recess 12, and like the same, provided'with a bearing.metal l16.

The membery 11 has near the corners, longitudinally `extended threaded studs 17 passingthroughy suitable openings" 18, inv the member 14. Clamping nuts 19and lock nuts 20 are screwed upon the threaded, prol jecting ends of the studs and serve to clamp the two bearing members together in the custo-mary manner. If so desired, the outer member 14 of the bearing may be provided with a strengthening rib 21.

The outer bearing member sides, is cut away to form triangular recesses 22, the apexes of which rare centrally disposed with respect to the side-'faces of the clamping member, which terminate substantially at the outer edges of the lateral facesin which the recesses4 areformed, as is clearly shown in Figs. 1 and 2. The member 14 has formed therein openings 23 each extendingffrom the outer face ofthe member tov one .of the recesses .22 at the apex thereof. Mounted within4 each of the recesses 22'is a' pair of wedges 24, similarly formed and oppositely disposed, so that normally, the wedgessubstantially fill the recesses 22. lThe wedges, at their adjacent faces are cut away so that when they are in juxtapsition they forin a `triangular opening 25 in which is receiveda correspondingly-shaped lug 26 of a threaded adjustingmember 27 'located in one of the openings 23. The lug 26 is in effect a forward oset of the adjusting member, and when moved toward theapex of the recess and the outer ends of 22 serves to spread or to force apart the wedges 24, as is shown in Fig. 3, whereby the bearing members are correspondingly separated. An adjusting nut 28 having a collar or extension 29 in the suitably formed recess 23 is screwed upon each of the threaded adjusting members. By means of these nuts the members can be operated as will be readily understood, to spread the wedges 24. rlhe latter at their inner ends have cut-away parts 30 to admit the lower end of the adjusting member which carries the triangular lug 2G. At the other ends, the wedges likewise have round, elongated cutaway parts 31 in which are received the studs 17, and which permit the wedges to be moved in the directions of their lengths. Associated with the adjusting nuts 28 are loclr collars 82 having peripheral serrations 33 adapted to be bent down over the edges of the bearing member 14 to hold the adjusting nuts.

In the initial adjustment of the bearing when it is provided with new bearing metals, the wedges 24 are spread apart as far as possible. The bearing metals are so proportioned that they fit accurately with this adjustment of the bearing and are thus normally disposed with respect to the member journaled in the bearing. The nuts 19 and 20 are tightened and the bearing is ready for use. When it is necessary to readjust the bearing to take up wear, the adjusting nuts 28 are suitably turned so that the adjusting members with their lugs 26 recede toward the bearing member 1l. By tightening the nuts 19 and 20 the bearing member 14 can subsequently be moved toward the bearing member 11, until the bearing is again in normal condition and the metals fit snugly about themember journaled in the bearing. When this adjustment has been effected the adjusting nuts are again locked by means of the collars 32.

Having thus described my invention I claim as new, and desire to secure by Letters Patent 1. In a bearing, two relatively movable members having bearing material for the part journaled therein, one of said members having a triangular recess at each side thereof the apex of which is transverse to the journal; a pair of wedges in each of said recesses intermediate said members operable in a direction parallel to the journal; means in said recesses intermediate said wedges for operation of the said wedges; and clamping means associated with said members whereby the same are normally forced against said wedges intermediate said members.

2. In a bearing, two relatively movable members having bearing material for the part journaled therein, one of said members having a triangular recess at each side thereof, said recesses having the apex of same transverse to the part journaled therein; a

pair of wedges in each of said recesses at each side of said apex and intermediate said members; means in said recesses intermediate said wedges and central with said apex for relative adjustment of said wedges in a direction parallel to said journal; and clamping means associated with said members whereby the same are normally forced against said wedges intermediate said members.

3. In a bearing, two `relatively movable members having bearing material for the part journaled therein, one of said members having a triangular recess at each side thereof with the apex transverse to the journal; a pair'of substantially identical wedges in each of said recesses intermediate said members; means in said recesses intermediate said wedges and central with saidv recesses for relative adjustment of said wedges in a j direction parallel to the journal; and clamplng means associated with said members whereby the same are -normally forced against said wedges intermediate said memers.

t.
